Tuesday means weekly outage day for mysql database backup/compression. Since the replica got messed up during the duet of crashes over the weekend, we are using this backup today to recover the entire replica database from scratch right now. Should be ready to go in a few hours or so. I think the regular boinc stats xml dumps also broke over the weekend but those should be generating normally again now.

The secondary science database is also suffering some kind of malaise. Not sure what the deal is, but it's slowing down my NTPCkr web site development. I thought it was excess disk activity on the system (caused by writing a primary database backup image to one of its spare drives) wreaking havoc, so I waited for that to end, but still no dice. Had to stop/restart the engine and even then it went through some phase of vague recovery before I could access it again.

Finally got that replacement sata card for the datarecorder down at Arecibo. Jeff and I tested it in a system up here (mostly to make sure we didn't need to update its firmware) and I just put it in a box heading to Puerto Rico (along with a set of blank data drives). Hopefully it'll be a quick swap and we'll be back to recording data again.

Jeff and I are really getting into the mode of programming/development. I think we found a way to speed up the NTPCkr a little bit more this morning, which is always a good thing. I'm still mostly working on internal visualization tools (with some simultaneous thought to what the first rev of the publicly available pages may look like). Don't get too excited yet - it's mostly just a table of numbers.

Are we just backlogged or is there a problem? I can't seem to upload. I'm getting the project may be down notice and backing off.

It's just the normal post-downtime fight for bandwidth.
